Question

You decide to install a new window in your bedroom. What is the area of the wall you will need to remove in order to install the new window?

Answer 1

Let's begin by identifying key information given to us:

This is a composite shape composed of a semi-circle & a rectangle. The area of the wall is equal to the area of the rectangle

AREA OF RECTANGLE

`\begin{gathered} Area(rectangle)=length* width \\ length(l)=12ft \\ width(w)=10ft \\ Area(rectangle)=12*10=120 \\ Area(rectangle)=120ft^2 \end{gathered}`

AREA OF WALL = Area of Rectangle

AREA OF WALL =120

AREA OF WALL = 120 sq.ft
